Design:Descriptive study.Animals:Fifty native turkey poults suffered from growth retardation,long standing diarrhea or both were obtained from native turkey raising areas of Iran (northern and western provinces) Procedure:The clinical signs and symptoms of poults were recorded and fecal samples were taken and stained with modified Zeih1-Neelsen method. Poults were sacrified and necropsied tissue samples collected from different parts of small and large intestine and processed for histopathological examination. Statistical analysis: kappa & Mcnemar test. Results: Histopathological studies revealed that 13 out of 50 cases were infected with cryptosporidium spp.' Histopathologic changes were seen as of hyperplasia of epithelial cells, hypertrophy of crypts , atrophy , fusion and shortness of the villi and increase in the number of leukocytes in the lamina propria' Furthermore, 5 out of 13 cases were positive for cryptosporidium organisms in fecal smears in stainig with modified Zeih1-Neelsen method.The results of fecal examination and histopathological study was not correlated. Clinicat implications: since the cryptosporidium is pathogenic to turkeys the infection is hazardous not only for native turkey husbandary but also for infected turkeys. This conditin could be a source of infection for industrial poultry production. Furthermore, the best cryptosporidial diagnostic method is histopathologic examination.}, keywords = {cryptosporidium spp,Iran,native turkeys}, title_fa = {مطالعه آسیب شناسی کریپتوسپوریدیوزیس در بوقلمونهای بومی ایران}, abstract_fa = {o3*rl9 .-lri,rt5:il9 .r*l;ir.q31oWl A* tl ,lltl.f f .Slffr^E91 . r,t# y.olg 4 :* ri'.,9 y,:o;e r9l S.rltaal 6;EolUil.p.5t'e/r'lit 'ui'reg: :7tb Jf,S/"1 q & a;ia 1 - tl .1ro r9,u}, keywords_fa = {}, url = {https://jvr.ut.ac.ir/article_24561.html}, eprint = {https://jvr.ut.ac.ir/article_24561_e5651c7ab9b15e31c1edce4f89cd7652.pdf} }
